Sylvania 5Y3 5Y3GT/G JAN-CHS-5Y3GT/G VT197A Milspec Vacuum Tube Rectifier Black Plate And The Raiders I have played this tube

I have played this tube in my Bottlehead Crack headphone amplifier and it sounds excellent

All measured 2100 micromhos where new/nominal is 2000 and minimum (65%) is 1300

I do not recommend them for applications with vibration

74 and 78 where minimum (65%) is 58

I am playing them in one my Radio Craftsmen RC2 mono blocks as I write and they sound super even though they test poorly and have that oxide isse
